Hello,
I just replaced my old 02 sensor, it had about 50 but worked fine. I didn't test readings before I removed it, but the car smogged well a few months back and changing AMM settings were noticed during smog test. I've recently done many mods to the car and today I replaced the stock 02 with a universal bosch 02 sensor,Part #13913. The car ideals fine, no hunting and the car seems to run about the same as before it's replacement. My local Saab shop said the voltage readings seemed different than what they normally see. Normally they see a constant .02 to .9v up down saw tooth wave. They said mine went from .02 to 2.2v then stayed high then dropped then stayed high. Should I be worried will the generic 3 lead Bosh 13913 work. Yes we swapped the white wires and it's running well but this readings are different from what the shop normally see's?? Any advice before I make dyno runs? Will this 02 be fine, it cost 45$ vs. 175$ for a stock Saab 02.
I have my 87 9000 T it's now running great and I'm ready to dyno the car this week. I just upgraded to Turbo added a AID distributor retard and cleaned the intercooler. Now I'm getting 4/5ths red boost the cars runs much cooler 1/2 on the temp gauge and doesn't detonate at 18 0r 20 BTDC. I've found 18% allows me to hold boost with out flutter that happens at 20%. I wanted to replace my 02 sensor before I dyno my car so things are constant and I have less variables. I want to try making a few dyno runs. I have an hour to tweak the car and run multible tests. I.E: timing, AMM, and install the original air box, then set a base line for comparison.
